-the device is small
-the amplifier is very cheap
-the device is easy to use

-screw terminal is made out of cheap material, it should be replaced by a dc power connector
A low pass should be placed at the output, this amplifier creates a lot of interfering signal, you should also use it in a case made out of metal and the wire to the loudspeaker should be as short as possible.
Please replace the screw terminal with a dc power connector.
A case for this amplifier would be a nice "addon".
If you need a small amplifier for low volume application, buy this, if you need more power, you should buy something like SKU 44123.
